IMPROVEMENT IN DEVICES FOR MAKING CORES FOR AXLE-BOXES.

Specification forming part of Letters Patent No. 13l,007, datedSeptember 3, 1872; antcdated August 27, 1872.

To all whom it may concern Be it known that I, HENRY KELLOGG, ofMilford, in the county of New Haven and State of Connecticut, haveinvented a new Device for Making Cores for Gastin g Axle-Boxes;

- and I do hereby declare the following, when taken in connection withthe accompanying drawing and the letters of reference marked thereon, tobe a full, clear, and exact description of the same, and which saiddrawing constitutes part of this-specification and represents, in-

Figure l,a side'view; in Fig. 2, a top view; and in Fig. 3, a verticalcentral section.

This invention relates to a device for male part is pressed down ontothe sand in the box thus formed itwill gather-sufficient sand into thebox to make the core of the required density. H

A is one part, and B the other part, of a core-box, the interior of thecore-box, when the parts are together, as in Fig. 1, corresponding tothe size and form of the core to be produced. These two parts arefitted, respectively, to a frame or handle, A B, and these two handles,at a distance from and by preference in line with the division of thebox, as at a, are hinged together, so that one may be raised and turnedup entirely away from the other. To the part A two sides, 0 D, arehinged, so. as to turn away from the box, as denoted in Figs. 1 and 3,or fold up against the box, as denoted in broken lines, Fig. 3. 'On thearm or other part B projecting studs d d are formed, extending downward,and so that when the part B has entered be; tween the two sides in itsdownward movement, as denoted in Fig; 3, the said studs will strike uponprojections f on the said sides, and, as the part B is fully closed willconsequently turn the sides 0 D from the box, as seen inFig. 3.

To form a core, throw the part B up entirely away from the other part,turn the sides 0 D up against the part A, as denoted in broken lines,Fig. 3, and fill the space formed by the said sides with the sandprepared for forming the core; then bring the other part B down onto thesand and press hard thereon. The part B will descend, gathering betweenitself and the part A sufficient sand to form the core,

at the same time opening the sides 0 D to allow the surplus sand to passaway from the box. Thus pressed together, the surplus sand having fallenor been brushed away, the core is complete, and may be removed byopening the box; To retain the two sides in their open position a bar,n, provided with a suitable spring, s, bears against a fiat surface onthe said sides when in such position, as seen in Fig. 3; or, ifpreferred, separate springs for each side may be employed.
